Overall it was a good place to stay, but there were a few things what went wrong :
1. Check-in. The keys from the apartment are in the mailbox, but the mailbox is inside, behind the doors that can be only opened from inside or by card, which is in the mailbox, so you cannot get in without the help of the third person. You need to sneak into the building when someone is going out and it's hard to do it on a late evening. That's it's totally wrong.
2. The apartment was not 100% clean when we arrived, there was some dust, things in the trash bin, and hairs on the pillows and sheets.
3. One day there was no electricity because host didn't pay the electricity at the time.
The area is pretty ok, close to BTS station and few foods stop around. Nice swimming pool but I don't' understand why it's directed to the east side, instead of west side for better views. On the east side, you have literally nothing when on the west side you have a view for the Bangkok center and sunset. Poor gym.
